This code is for reading the I/K Bus in BMW Cars. With this code you can read sensor values, control lights, windows and much more. I shared schematics with optocouplers and chips. I used Arduino nano as microcontroller, but you can use another microcontrollers like STM32, ESP32 and much more.

I will share more information about I/K Bus protocol and communication later. Stay tuned 😉.

You can also see my other car projects:

1. Тhis project is for BMW with I/K bus system.
2. Тhis project is for Cars with CAN Bus.
3. Тhis project is for Cars with ISO9141 and ISO14230 protocols.
4. Тhis is my OBD2 CAN Bus Communication Library for Arduino IDE.
5. Тhis is my OBD2 K-Line Communication Library for Arduino IDE.

This protocol applies to the bus system in the models listed below.

1. Clone this repository or download the .zip file
2. Open the .ino file with Arduino IDE
3. Select your board (e.g., Arduino Nano, ESP32)
4. Set the correct COM port and upload the code
